z-transform fir low-pass filter fourth order
Hi
I'm studying RF filters.
How can I display the characteristics(magnitude and phase vs frequency) of
RF filters? Which tools should I use?
Please help me.
oh, thank you very much..
could you tell me why the resistance looking into the source is 1/gm and
the resistance looking into the drain is ro?
and I can't understand why the resistance looking into the source of M2 is
approximately 1/gm2..
Why is my answer is wrong? in my case, I thought the...
oh, thank you for your reply.
But I know how to analyze small-signal model.
That I want to know is how to find the resistances intuitively.
For example, here is a common-source amp.

Hi. I have some trouble in understanding resistance.
The reference is 'CMOS Circuit Design, Layout, and Simulation' by Baker. (1E)
In the chapter 22 Amplifiers
Vout/Vin = (resistance in the drain) / (resistance in the source).
Now, I want to find the resistance in the drain and resistance in...
